Applying ergonomics to nurse computer workstations: review and recommendations

Development and validation of a Nurse Station Ergonomics Assessment (NSEA) tool

Background

Nurse stations are one of the primary units for supporting effective functioning of any hospital. They are important working environments that demand adherence to known ergonomic principles for the well-being of both staff and patients. The aim of this study was to develop a psychometrically tested tool for the assessment of the ergonomic conditions of nurse workstations in hospitals.

Methods

Ten hospitals, with a total of 133 nurse stations participated in this mixed-methods research. The domains and items of the tool were developed based on a literature review, an experts’ panel, and interviews with nurses.

Results

The final nurse station ergonomic assessment (NSEA) tool has good psychometric properties. Validity was assessed by face validity and content validity. Reliability was evaluated using inter-rater agreement and test-retest reliability analyses with a four-week interval between assessments. The NSEA is comprised of 64 items across eight domains: layout and location (7 items), workspace (11 items), security-safety (5 items), environmental conditions (8 items), counter (8 items), chair (13 items), desk (9 items), and monitor (3 items).

Conclusions

The NSEA adds to the literature a tool for managers to ensure they comply with legal requirements and support best practice for those working on hospital wards. The NSEA can be used to identify challenges for healthcare professionals who use nurse stations and support the execution of targeted interventions to improve human-environment interactions.

The use of human factors methods to identify and mitigate safety issues in radiation therapy

BACKGROUND AND PURPOSE

New radiation therapy technologies can enhance the quality of treatment and reduce error. However, the treatment process has become more complex, and radiation dose is not always delivered as intended. Using human factors methods, a radiotherapy treatment delivery process was evaluated, and a redesign was undertaken to determine the effect on system safety.

MATERIAL AND METHODS

An ethnographic field study and workflow analysis was conducted to identify human factors issues of the treatment delivery process. To address specific issues, components of the user interface were redesigned through a user-centered approach. Sixteen radiation therapy students were then used to experimentally evaluate the redesigned system through a usability test to determine the effectiveness in mitigating use errors.

RESULTS

According to findings from the usability test, the redesigned system successfully reduced the error rates of two common errors (p<.04 and p<.01). It also improved the mean task completion time by 5.5% (p<.02) and achieved a higher level of user satisfaction.

CONCLUSIONS

These findings demonstrated the importance and benefits of applying human factors methods in the design of radiation therapy systems. Many other opportunities still exist to improve patient safety in this area using human factors methods.

Nurses' health: work and family influences

Nurses represent the largest group of professional caregivers. Most are also informal caregivers for family members, including children, parents, spouses, and other relatives. The impact of these caregiving roles, individually and in combination, has important implications for the health of nurses. This article focuses on nurses' health, emphasizing research on the influence of the work and family stress on physical and psychosocial dimensions of health. Health and safety concerns of nurses are discussed and findings from longitudinal studies of nurses' health are presented. Challenges for maintaining a healthy nursing workforce for the future are discussed.
